ABSTRACT:
An amplification apparatus is provided that includes a plurality of gain stages including a first gain stage having first and second transistors and a second gain stage having third and fourth transistors. A plurality of replica stages may also be provided that includes a first replica stage and a second replica stage. Each replica stage may correspond/match one of the plurality of gain stages. An amplifying device may be provided to adjust a body potential of at least the first transistor of the first gain based on an output of the first replica stage and an output of the second replica stage.
